ABSTRACT:
An arrangement for spatially resolved acquisition of an object which is illuminated by an illumination arrangement, wherein a relative movement is generated between the illumination arrangement and the object by moving the object and/or the illumination arrangement and, in addition to at least one confocally arranged detection element for confocal acquisition of the light coming from points on the object, there is provided at least one additional detection element for the acquisition of object light at least posterior in time to the confocal acquisition. For at least two-dimensionally spatially resolved measurement of time processes, especially of fluorescence decay times, preferably at the ocular fundus, using a scanning laser ophthalmoscope, the radiation receiver is at least a series of detectors which are arranged in such a way that there is a series of additional detector elements in addition to the confocal detector element at least subsequently in the scanning direction.
